{SPECIFICATION Application 'niet rute 10,1899.

To all whom it may concern:

Be it known that I, HORACE HURLBURT, of Leavenworth, Leavenworth county,-Kansas, have invented certain new and useful Im provements in RevolvingElevatorsor Der- A rick-Cranes, of which the following is aspecipleasure bent around in the air.

In order that the invention maybe fully understood, reference is to behad to the accompanying drawings, in which- Figure 1 represents a view,partly in elevation and partly in vertical section, of a portableelevator or derrick-crane constructed in accordance with myinven tion.Fig. 2 is a horizontal section taken on the line II II of Fig. 1. Fig. 3is anenlarged inverted plan view of the platform upon which the operatorWalks tov 'revolve thedevice.

Fig. 4 is a detail view, enlarged, to show the means for maintaining van object at any desiredaltitudej v In the said drawings, 1 designatesthe front wheels, connected by the axle 2, and 3 the rear Wheels,connected by the axle 4, and said axles are in turn connected by abed-plate 5, having a pivoted connection with the front axle through themedium of the fifth-Wheel 6, and projectingforward from said front axleis the tongue 7, to which draft-animals may be hitched inthe usual oranypreferred manner when it is desired to move the machine.

S designates a rear platform secured tothe rear axle and' braced by theinclined bars 9, and connected to said rear axle is a forked frame 10,having its rear ends connected to the bolts 11, (one only of whichappears) depending from the axle 12 of a pair of large wheels 13, abolster 14 being secured to the axle and provided with a fork or guidelfor a purpose which hereinafter appears.

, 16 designates a cast-metal socket-tube extending down through thecenter of the bedforming part of Letters Patent No. 634,577, datedoctober 10,1899.

Serial Nc. 720,061. (No model.)

plate 5 andprovided with pair of outwarc'lly-` projecting flanges 17,embracing and united to the bed-plate by means of the `bolts 1S, and asthis bed-plate is designed to receive a comparatively heavy weight saidbed-plate is trussed by means of the-truss-rod 19 extending through thelower end of the socket-tube and having its ends bolted tothe bed-platenear the front and rear ends of the latter,

M designates generally the mast, composed of the sectional stationarylower portion and an upper revolving portion. The sta tionary lowerportion consists of the rectangular part 20, seated at its lower end inthe correspondingly-formed socket-tube and of cylindrical formation atits middle, as at 21, and the su perposed rectangular part 22, formedwith ashoulder or enlargement 23 and a vertical hole or recess 24:.inits upper end. The part 22 is hinged to the part 20 by means of theplates 25 26, pivoted together at their outer ends, as at 27, so thatthe upper part of the mast may fold downto the position shown in dottedlines, Fig. 1, and rest in the guide-bracket 15. 'In order to secure themast in its vertical position, however, the parts 2O and 22 are providedwith the similar angle-plates 28, normally bolted together, as shown at29, and in order that the operators whose business it is to revolve theupper portion of the mast may accomplish the same with the leastdifficulty l mount a circular platform 30 upon the rectangular upperpart 22 of the stationary or lower section of the mast, said platformresting upon the enlargement 23, provided at a suitable point with aradial recess 31 fora purpose which hereinafter appears.

32 designates the upper or revolving portion of the mast, provided witha 'depenlin g cylindrical ystem 3 3, journ aled in the vertical holeV orrecess 24. The rotatable portion of the mast is furthermore providedwith a guide-sheave 34 at its upper end and with an opening or recess 35, through which extends and is pivoted to operate vertically thewalking-beam 36, said beam being braced or trussed by means of the cableor rope 37, which extends over the guide-sheave 34C and vis secured atits opposite, ends to the guide bolts or hooks-38, projecting from the4ends of the walking-beam.

ICO

. curedto the ends ot' thewalking-beam, are

the'links 40, pivoted, as at 4l, tothe arms of the baskets, cages, orplatforms 42, adapted to receive humanor any other kind of freight. Inorder that motion may be' imparted to this walking-beam to cause it tooseillate upon its pivot, I journalav sleeve 43 upon the cylindricalportion 2l ot' the lower or stationary part of the mast and support saidsleeve by means of acollar 44, said sleeve l being pro vided or formedwith a pair of stub-shafts`45, projecting forwardly and rearwardly andsupported at their outer ends by means ofy the arms 46 of the sleeve 47,journaled also upon said part 2l, oi" the mast and resting upon theupper end of the socket-tube. Ay pair of drums 48 are journaled uponsaid stub-shafts 45 and are connected to the eyebolts 39 of thewalking-beam by means of the cables 49, said cables extending aroundthe, guide-sheaves 50 and 5l, respectively, carried by the front andrear arms 4G ofy rotatable sleeve 47. The drums are provided withtubular extensions 52, which project through the arms 46 and areprovided lwith crank-arms 53 at their outer ends and inward thereof withthe disks 54,r provided with, a circular `series of openings 55, throughone or the other of which and the registering holein the correspon dingarm f 4G' a locking-pin 56 extends to lock the drums at the desiredpoint of adjustment, and consequently lock the walking-beam, with itsbaskets 42, at the desired elevation.

As it is necessary in the revolution of the upper part of the mast thatthe mechanism for oscillating the walhing-beam and the sleeves carryingsaid mechanism shall rotate synchronously, the arms 46 are connected bythe arms 57 to the outer ends of the handles 58 of a sleeve 59, fittingupon the squared portion of the rotatable or upper portion of the mast,which handles 58 form a convenient means for an operator or a pair ofoperators upon platform 30 to impart rotatable movement to the mast andthe connected parts, said operator simply grasping the handle 58 andpushing the same before him as he walks around on the platform in thedirection in which the mast is to revolve.

Supposing the device is to be used as a Whirl-around, the walking-beamis operated to dispose one of the baskets or cars upon the ground. Thepassengers are arranged comfortably in this basket, and then theposition of the walking-beam is reversed by an operator standing on theplatform 5 at its front end and an operator standing on the platform 8,said operators turning the drums in the proper direction, as will bereadily understood, until the unloaded car is on the ground. Thepassengers for this basket step in, and then the drums are manipulateduntil the walking-beam assumes a horizontal position, if desired, atwhich point it is locked by the insertion of the locking-pins 56 throughthe registering holes' 55 andthe holes in the sleeve-arms 46'. riheoperators now step upon the platform 30 at opposite sides of the handleand, walking forward, push the handle around in front of them, andthereby cause the upper portion of the mast, together with the partsconnected thereto and mounted rotatably upon the lower or stationarypart of the mast, yto revolve `at thek desired speed. Should it bedesired to elevate as high asH possblethe basket 42 at the front side ofthe mast, rit is obvious that the corresponding cable 49 will enter theslot 3l of the platform 30, so thatthe latter shall not interfere withthe operation, as it undoubtedly would if such slot were not provided byreason of the forward drum being located so close to the mast. Byreference to Fig. l it will f be seen that when the front cable 49extends upward through the guide-sheave 50 at the same angle that thecompanion cable extends in said iigf iermit the sleeve 59, rovided withhandles l l@ 58, to be disconnected from said arms. The

dismantled parts of the machine may then be loaded upon the wheeledframe at oppo site sides of the mast, and in this condition the machinemay be as conveniently conveyed from place to place as the ordinaryfield-pieces used by the army.

From the above description it will be apparent that I have produced amachine of the character described which possesses the features ofadvantage enumerated as desirable in the statement of invention andwhich is of simple, durable, and comparatively cheap construction, andwhile I have illustrated the preferred embodiment of my invention I wishit to be understood that I reserve the right to make any and all changesin the same which do not involve a departure from the spirit and scopeof the invention.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is
